Lewisham Homes keep it clean with MagnaClean
Lewisham Homes - managing and maintaining the council houses and estate owned by Lewisham Council. This includes 13,700 social housing tenancies, 5,100 leasehold properties and the interim management of 3,400 additional properties.
1. To reduce the number of central heating breakdowns across the housing stock.
2. To reduce maintenance and breakdown call-outs and subsequent disruption to homes and tenants.
3. To deliver significant budget savings in central heating system maintenance.
4. To extend the life of the system pump, heat exchanger and boiler.
Problems with plate heat exchangers which were becoming blocked with black iron oxide sludge and breaking down, was not uncommon at Lewisham Homes. Repairing plate heat exchangers was a challenging and costly task with limited access inside boiler houses and maintenance and repairs taking up to a day to resolve; causing prolonged and unnecessary disruption to homes and tenants.
ADEY provided 20 of its MagnaClean Industrial filters to
cope with the size and scale of the communal heating
system, removing virtually 100% of the offending
magnetite sludge. As water passes through the boilers
and plate heat exchangers, MagnaClean Industrial filters
capture and trap the black iron oxide sludge, removing it
from the system permanently. Some engineers believe it
is only necessary to flush out the sludge periodically, but
MagnaClean provides ongoing heating system protection
by preventing particles leeching back into the system
water causing the same problems to occur.
ADEY’s magnetic filtration technology is actively
reducing maintenance call-outs and the breakdown of large
communal heating systems. Significant sludge deposits have
been removed from the system, allowing enhanced central
heating system performance, without disruption to homes and
“With our central heating systems getting older, call-outs and
the need for repairs were becoming more frequent and
increasingly expensive. We took the decision to replace some of
the boilers but realised we needed to take further measures
to ensure they stay in good working order for as long as
possible. It’s a big investment for any local authority or housing
association during a very difficult time when all costs need to
be justified, but we’ve found it to be worth it for the savings it
brings to both us and our tenants.”
